The floating caliper brake used in the front car wheel is shown in the following figures. The caliper supports a single floating piston actuated by hydraulic pressure. Two annular pads, ri=100 mm, ro=140mm, subtend an angle of 110°, have a coefficient of friction of 0.4, and are actuated by a pair of hydraulic cylinders 40mm in diameter. The torque requirement is 1350 N.m. For uniform wear (a) Find the largest normal pressure pa. (b) Estimate the actuating force F. (c) Find the equivalent radius re and force location r. (d) Estimate the required hydraulic pressure.
